When PRO • pHx is added to acid in the ratio of 1/2% to 1% to the total acid volume, the treatment drops metals, organics and impurities which build up in the acid during the pickling process out of solution. Filtration removes the impurities from the acid and this "frees up" the remaining available acid, restoring and extending the acid life indefinitely. The only additional acid needed is the small amount of replacement acid ("Acid Spike") necessary to replace the acid lost during production drag out and evaporation.

PRO • pHx Provides a First Generation Answer for the High Cost of Acid and Acid Disposal.
